Two British citizens have been killed in Pakistan by missiles fired from US drones, according to the men’s friends and families. They are the latest reported casualties in America’s growing campaign against suspected militants.

Ibrahim Adam and Mohammed Azmir, who had both been suspected of terrorist activities, are believed to have died in a single strike in Waziristan at least three months ago. Adam appears to have been able to leave Britain and enter Pakistan despite absconding from a control order. Azmir’s assets were frozen by the Treasury last year.
